Definitions
- the invention relates to an air filter element with a cylindrical tube-shaped filter bellows, which is each end closed with an end plate and a method for producing
- End plates are necessary in order to make a seal of the filter element in an air filter housing and to force the intended radial flow path through the filter bellows.
- At least one end disk has an annular sealing body on the outside facing away from the filter bellows.
- the sealing body is conventionally made by inserting the end disk into a casting shell and then filling a liquid, polymeric material which flows into an annular aperture or depression on the end plate and / or the casting shell. After curing or crosslinking, the casting shell is removed so that a sealing surface is exposed at the end plate in the area of the previously existing annular gap.
- the production shown is time consuming and correspondingly expensive. Due to the curing time or the necessary time for crosslinking of the polymeric material, a certain, non-shortenable cycle time in the series production of Fiiterettin is necessary.
- the object of the invention is thus to be able to produce generic air filter elements faster and cheaper.
- an end plate comprises an air filter element outwardly facing support member which is iaseriichi trimelle at least in some areas, and a filter bellows facing connection layer, which at least in some areas is laser light absorbing and which sealingly connects the filter bellows with the carrier element.
- Such an end plate has the advantage that a welding with a filter bellows on laser beams is possible and thus no pot lives of adhesives must be considered in the manufacture of the air filter element.
- the carrier element is irradiated, the underlying connection layer melts at least partially, so that the Füterbalg can be pressed with its front side in the melt of the connecting layer and thus a mechanical connection between the filter bellows and end plate is made and a seal is effected.
- Error spots in the connection or detachment of the connecting layer from the carrier element can be recognized from the outside through the transparent carrier element when the connection layer is chosen sufficiently thin.
- a layer thickness of 3 mm is sufficient to securely connect the filter bellows to the end plate.
- the bonding layer consists of a thermoplastic elastomer, which can be produced by injection molding.
- the tie layer can be made in a separate body, which is then combined with the body forming the support member of the end plate.
- both layers are produced at the same time by means of 2 component injection molding.
- a further advantage is when the end plate is the same equipped with a ring seal in order to produce a sealing connection of the air filter element with an air filter housing without separate seals must be made and installed.
- a preferred embodiment provides that the support element of the end plate has at least one exposed to the outside sealing body, which passes in particular through a recess in the support member of the end plate and connected to the inside of the end plate with the connecting layer o ⁇ even integrally with this together is trained. This means that no further production steps have to be made.
- a transparent carrier element that is to say a carrier element, which to a predominant extent! is transmissive to the light radiation of an inserted laser device with a specific wavelength is irradiated.
- the laser radiation which has passed through the carrier element is absorbed in the connecting layer at least to such an extent that softening or melting of the connecting layer takes place. Duration and intensity of the irradiation are chosen so that the fastest possible melting is achieved, so that the heat input into the adjacent transparent support member is kept as low as possible and deformation of the transparent support member is largely avoided.
- the filter bellows only needs to be pressed into the melt.
- the cooling leads to the re-solidification of the connecting layer, embedded with the solidification in the thermoplastic mass edge regions of the Fiiterbalgs.
- a receiving element is used, which is also at least in those portions of laser light transmissive, behind which are melted areas of the connecting layer to position. Otherwise, the manufacturing process remains unchanged.
- the receiving element supports the end plate and helps to maintain the geometry of the carrier element under the influence of heat.
- the use of an additional receiving element in the production is advantageous if connecting layer and sealing body are made in one piece and form a connecting element.
- the sealing body then emerges at an annular opening of the end plate to the outside, wherein the outer side of the end plate in the manufacturing process is always the downwardly swept surface. Without additional support, it could lead to a flow out of the melt and thus to the destruction of the already preformed seal.
- a particularly profiled support portion of the receiving element is positioned in particular below the outwardly penetrating sealing body.
- An additional support portion may be in the form of a flute-shaped edge which is positioned inside a central recess in the annular end disc with a spacing with respect to the inner edge of the annular end disc which corresponds to the thickness of a sealing lip to be formed there. Without an additional support portion, the formation of a radially acting sealing lip on the end plate would not be possible.
- the receiving element for the end plate thus represents in this variant of the method according to the invention is a casting shell, which contributes to the formation of parts of the seal body and the connecting body.
- FIG. 1 a filter element in a perspective view
- Fig. 2 shows a detail of a filter element of a first embodiment in a section
- Fig. 3 shows a filter element of a second embodiment in a section detail.
- Fig. 1 shows an air filter element 10 with a cylindrical tube-shaped filter bellows 11 made of an air-permeable filter medium. At both end faces each end plates 20 are placed and connected airtight with the filter bellows 11. At least one of the end disks 20 is, at least in the use state of the air filter element 10, annular, so that a central inner flow channel is opened.
- Fig. 2 shows a first embodiment of an end plate 20 with a matching receiving element 200, in which it is inserted.
- the end plate 20 comprises a lower support element 21 and a connection layer 22.1 located above it.
- a filter bellows 11 is attached.
- the receiving element 200 supports a sealing body 22.2, which occurs at an opening of the outer support member 21 on the end plate 20 to the outside.
- the Sealing body 22. 2 is connected to the actual connecting layer 22. 1, so that an integral connecting element 22 is formed, which is fixedly connected to the carrier element 21.
- Receiving element 200 and support member 21 of the end plate 20 are permeable to the laser light, which is irradiated according to the arrows in Fig. 2 from below and reaches into the connecting layer 22.1, where it is absorbed. Subsequently, only the filter bellows 11 still needs to be sunk into the melt thus produced in the bonding layer 22.1 and the process for the other side of the filter bellows repeated to complete the production of the air filter element according to the invention.
- FIG. 3 shows a further exemplary embodiment of an end disk 20 "with an associated receptacle 200.
- an axial sealing portion 22, 2 ' is supported by a supporting portion 202' of the receiving element 200 '
- An inner annular section 23 'of the end plate 20' is intended to be covered at least partially with its lip surface by a lip seal, for which purpose a support section 203 'is formed on the receiving element 200 "which serves as a die for forming the lip seal.
- a cavity 205' is formed, in which the lip seal is formed.
- the support member 21 'of the end plate 20' as well as the Conseiement 200 ' are again permeable to laser light of a certain wavelength, which is radiated from below through the receiving element 200' and the support member 21 'until the bonding layer 22' melts.
- a projection is on the ring portion 23 'of the support member 20 ⁇ provided which allows latching of the end plate 20' to a compatible projection on the ring portion 203 'of the receiving element 200'.
- the end plate 20 'thus hangs during the entire manufacturing process in a defined position on the receiving element 200', so that in particular the tightness is granted at the transitions and an uncontrolled outflow of melt is prevented.
